Molar concentration (also called molarity, amount concentration or substance concentration) is a measure of the concentration of a chemical species, in particular, of a solute in a solution, in terms of amount of substance per unit volume of solution.
Transparency and translucency. Dichroic filters are created using optically transparent materials. In the field of optics, transparency (also called pellucidity or diaphaneity) is the physical property of allowing light to pass through the material without appreciable scattering of light. On a macroscopic scale (one in which the dimensions are ...
A glass electrode is a type of ion-selective electrode made of a doped glass membrane that is sensitive to a specific ion. The most common application of ion-selective glass electrodes is for the measurement of pH. The pH electrode is an example of a glass electrode that is sensitive to hydrogen ions.
Photochromic lens. A photochromic eyeglass lens, part of the lens darkened after exposure to sunlight while the other part remained covered. A photochromic lens is an optical lens that darkens on exposure to light of sufficiently high frequency, most commonly ultraviolet (UV) radiation.
Kristallnacht ( German pronunciation: [kʁɪsˈtalnaχt] ⓘ lit. 'crystal night') or the Night of Broken Glass, also called the November pogrom (s) ( German: Novemberpogrome, pronounced [noˈvɛm.bɐ.poˌɡʁoːmə] ⓘ ), [1] [2] [3] was a pogrom against Jews carried out by the Nazi Party 's Sturmabteilung (SA) and Schutzstaffel (SS ...
In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture. Several types of mathematical description can be distinguished: mass concentration, molar concentration, number concentration, and volume concentration. [1]
Conservation refers to the ability to determine that a certain quantity will remain the same despite adjustment of the container, shape, or apparent size. [1] Other conservation tasks include conservation of number, substance, weight, volume, and length. Perhaps the most famous task indicative of centration is the conservation of liquids task.
Glass. Glass is an amorphous or non-crystalline solid. Because it is often transparent and chemically inert, glass has found widespread practical, technological, and decorative use in window panes, tableware, and optics. Some common objects made of glass like "a glass" of water, "glasses", and "looking glass", have become named for their ...
Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass.
In optical physics, transmittance of the surface of a material is its effectiveness in transmitting radiant energy. It is the fraction of incident electromagnetic power that is transmitted through a sample, in contrast to the transmission coefficient, which is the ratio of the transmitted to incident electric field.
